What Year 7 Maths students should achieve
Coverage is judged against the achievement standard — not by ticking every content description. These are the official Year 7 Maths standard sentences this code builds towards:
- Students classify polygons according to their features and create an algorithm designed to sort and classify shapes.
- They represent objects two-dimensionally in different ways, describing the usefulness of these representations.
- Students choose between equivalent representations of rational numbers and percentages to assist in calculations.
- Students interpret data in terms of the shape of distribution and summary statistics, identifying possible outliers.
- Students solve problems involving addition and subtraction of integers.
- They solve linear equations with natural number solutions.
The Measurement progression either side of AC9M7M01
A class can only meet this descriptor if they were taught the one before it. If yours hasn't, that's where the lesson starts — not here.
Taught before · Year 6
- AC9M6M01convert between common metric units of length, mass and capacity; choose and use decimal representations of metric measurements relevant to the context of a problem
- AC9M6M02establish the formula for the area of a rectangle and use it to solve practical problems
- AC9M6M03interpret and use timetables and itineraries to plan activities and determine the duration of events and journeys
Builds towards · Year 8
- AC9M8M01solve problems involving the area and perimeter of irregular and composite shapes using appropriate units
- AC9M8M02solve problems involving the volume and capacity of right prisms using appropriate units
- AC9M8M03solve problems involving the circumference and area of a circle using formulas and appropriate units
Other Year 7 Measurement codes
- AC9M7M02solve problems involving the volume of right prisms including rectangular and triangular prisms, using established formulas and appropriate units
- AC9M7M03describe the relationship between π and the features of circles including the circumference, radius and diameter
- AC9M7M04identify corresponding, alternate and co-interior relationships between angles formed when parallel lines are crossed by a transversal; use them to solve problems and explain reasons
- AC9M7M05demonstrate that the interior angle sum of a triangle in the plane is 180° and apply this to determine the interior angle sum of other shapes and the size of unknown angles
- AC9M7M06use mathematical modelling to solve practical problems involving ratios; formulate problems, interpret and communicate solutions in terms of the situation, justifying choices made about the representation
